Just trying to find some honest opinions on the B series engine. Tractor has nearly 1500 hours, doesn't smoke, and runs great. Does have an oil leak which I have not located yet. What's with all the heat shields on this engine? Are they TRUELY necessary?just looking for feedback Seemengineenginewwoulhold all that heat
